Conclusions
-
1.
The parameters of induction heating (temperature, heating rate, and duration of isothermal heating) have a significant influence on the fine structure of Kh18N9T stainless steel.
-
2.
Isothermal heating at 1100°C favors the dissolution of chromium carbides and increases the resistance of Kh18N9T steel to intercrystalline corrosion.
-
3.
There is a relationship between the susceptibility to intercrystalline corrosion of Kh18N9T steel and the distribution and amount of chronium carbides resulting from different conditions of induction heating: The steel is susceptible to intercrystalline corrosion when there are chronium carbides situated in lines along the grain boundaries or accumulated in separate areas.
